The unit is a low-profile 10' powered subwoofer with a built-in amplifier and blue ambient light that slips under a car or truck seat; the single biggest reason to buy is its space-saving design paired with substantial peak power, which delivers punchy low end for modern music styles while avoiding the bulk of a traditional enclosure.
